Starter Solenoid
The solenoid is a remote switch that connects the battery to the starter motor
when the ignition switch is turned to START. The solenoid protects the ignition
switch from the high current drawn by the starter motor.

PTO Switch
The PTO switch provides battery voltage from the ignition switch to the PTO
clutch.
As part of the safety interlock system, the PTO switch will prevent the engine
from cranking/starting when in the ON position by preventing the start relay
from grounding through the hour meter.
